Вы не можете передавать ссылки в качестве реквизитов другим компонентам с именем prop без использования forwardRef для компонента. Вам нужно присвоить ему другое имя, чтобы оно работало, например, innerRefs.
Также для передачи ссылок в качестве реквизита компоненту Route используйте метод render prop
App .tsx
import React, { useEffect, useRef } from "react";
import { BrowserRouter, Route, NavLink, useLocation } from "react-router-dom";
import Home from "./pages/Home";
import "./styles.css";
const Header = ({ innerRefs }) => {
const location = useLocation();
useEffect(() => {
console.log("location", location.pathname);
switch (location.pathname) {
case "/about":
scrollSmoothHandler(innerRefs.aboutRef);
break;
case "/contact":
scrollSmoothHandler(innerRefs.contactRef);
break;
case "/hero":
scrollSmoothHandler(innerRefs.heroRef);
break;
default:
scrollSmoothHandler(innerRefs.homeRef);
break;
}
}, [location, innerRefs]);
const scrollSmoothHandler = innerRef => {
console.log("Triggered.");
console.log(innerRef.current);
innerRef.current.scrollIntoView({ behavior: "smooth" });
};
return (
<>
<NavLink to="/hero" activeClassName="selected">
Hero
</NavLink>
<NavLink to="/about" activeClassName="selected">
About
</NavLink>
<NavLink to="/contact" activeClassName="selected">
Contact
</NavLink>
</>
);
};
function App() {
const homeRef = useRef(null);
const heroRef = useRef(null);
const aboutRef = useRef(null);
const contactRef = useRef(null);
return (
<div ref={homeRef} className="App">
<BrowserRouter>
<Header innerRefs={{ aboutRef, contactRef, heroRef, homeRef }} />
<Route
exact
to="/"
render={routeProps => (
<Home
{...routeProps}
innerRefs={{ aboutRef, contactRef, heroRef, homeRef }}

)}

// More routes here.
</BrowserRouter>
</div>
);
}
export default App;
Home.tsx
import React, { Fragment, forwardRef, useRef } from "react";
import "../styles.css";
const Hero = forwardRef((props, ref) => {

<h1>Hero Section</h1>
</section>
